Interesting design by an argentine inventor. This gun externally powered by an small electric motor fires at 5000 to 6000 rounds per minute with a single barrel.

The advantages over a gatling type are less bulk, weight, and low power consumption ( 15 % of a gatling equivalent) The cartrigde remain always coaxial to the barrel between the loading , firing and expulsion, and does not have any reprocicating movement.

Disadvantage is a notable overheating of the barrel in long burst wich probably would work better with water cooling.

Attemps by the inventor ( Javier Fornes, from Mendoza) to sell and develop a 20 /30 mm variant with the budgetary cooperation of the Argentine military has been unsuccesful so far.

Less bulk and less weight than a gatling type machine gun. There is no contradiction on that, I forgot to put the "less" before weight.

The water cooling would add more weight thats for sure, but still is much lighter than the USAF multibarrel weapon.
